The LCM of 489,308,836,318 is 151666284.
Find LCM of 489,308,836,318 with Prime Factorization
| 2 | 489, 308, 836, 318 |
| 2 | 489, 154, 418, 159 |
| 3 | 489, 77, 209, 159 |
| 11 | 163, 77, 209, 53 |
| 163, 7, 19, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 163 x 7 x 19 x 53 = 151666284
Therefore, the lowest common multiple of 489,308,836,318 is 151666284.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
489 x 308 x 836 x 318 = 40039898976
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
489 : 1, 3, 163, 489
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
318 : 1, 2, 3, 6, 53, 106, 159, 318
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,308,836,318, is 1.
Now, the common factors can be found like this.
489:3x 163
308:2x 2x 7x 11
836:2x 2x 11x 19
318:2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 11 = 264
Therefore, the value for common factors is 264.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 40039898976/(1x264)
LCM = 40039898976/264
LCM = 151666284
Thus, we can understand that the LCM of 489,308,836,318 is 151666284.
